Description

Refrigeration
Technical field
The present invention relates to a kind of refrigerations for frozen food block, especially seafood and a kind of use according to this The method of the refrigeration frozen food block of invention.
Background technique
In the prior art, level board refrigerator is fairly common and for a variety of purposes, is especially in fishery It is freezed on ship, level board refrigerator is widely used.
Fresh fish is arranged in pallet, is then placed on pallet on the shelf of level board refrigerator.After the freezing, it will hold in the palm Disk is removed and is emptied, and allows frozen fish slab stiff at present that the part of adult fish is further processed or processed in carton package Deng.
The something in common of the level board refrigerator of these types is practical to be, level board refrigerator includes multiple horizontally disposed Freezing plate, these freezing plates can be raised and lowered in the vertical direction relative to each other by the actuation means of various arrangements.
In this way it is possible to open refrigerator or at least open the space between two freezing plates, to enter freezing Space between plate.Refrigeration is that the object (for example, fish) that should be freezed by freezing plate with it contacts to complete.
In order to generate this contact, freezing plate moves towards each other (usual all freezing plates move down), so as to cold The object and freezing plate of jelly are physically contacted.At this point, refrigerant recycles in freezing plate in a certain period of time, until to be frozen Object be frozen into solid or the temperature of at least interior of articles is in desired low-level.
At this point, actuation means are again started up, by forcing freezing plate to separate to open level board refrigerator, to allow cold The block frozen on plate is stored or is further processed from freezing plate mobile (being generally removed).
General Consideration when handling food is health and the ability for maintaining sanitation and hygiene security context.In this side Face, it is undesirable to all freezing plates must be cleaned between each refrigerating cycle.Refrigerating cycle is defined as the following time: refrigerator It opens and does not freeze pallet and be located on shelf；Freezing plate, i.e., be moved to and contact with the pallet being located on shelf by refrigerator closure； Refrigerant recycles in freezing plate, until reaching preferred temperature, hereafter freezing plate vertical shift, so as to accommodate frozen food Pallet disengage.At this point, freezing pallet is removed from freezing plate, and refrigerator is ready to receive filled with food to be frozen The new of product does not freeze pallet.This is also the understanding to the refrigerating cycle in the scope of the invention.
The considerations of hygienic aspect be naturally it is vital because food safety is extremely concerned.Use level board refrigerator A disadvantage be really that food to be frozen is located in pallet, and when freezing plate moves towards each other to start freezing and to follow When ring, freezing plate is contacted with food to be frozen.
In general, especially usually food is placed in pallet manually when food is seafood.In order to obtain substantially homogeneity Frozen food block, it is undesirable to there is air and excessive water in block, and therefore when seafood to be placed in pallet, sea It is fresh will be aheap more slightly higher than the size of pallet usually at certain.When food (seafood) and freezing plate contact, freezing plate will Food extrusion is into pallet, to make the horizontal equilibrium of food, so that they will almost be flushed and together with the top side of pallet When substantially completely contacted with freezing plate.
However, in this process, excessive water and juice from food may be squeezed out pallet and reach freezing The top surface of plate.This provides at least two disadvantages.
Firstly, since horizontal freezing plate be it is horizontal, liquid (water and juice from food) will be during refrigerating cycle It is retained on horizontal freezing plate, and to be freezed in a manner of identical with the food in pallet.In this process, pallet will It is freezed and is connected on freezing plate securely, so that when refrigerating cycle terminates and it is expected to remove pallet from horizontal freezing plate When, this is a troublesome process, because liquid-is currently ice, it is necessary to is broken, so as to remove pallet.
Second disadvantage is really, and between refrigerating cycle, frozen liq may thaw, and sets to be pushed out freezing It applies and finally falls on floor or on the side of refrigeration.This is quite antihygienic situation, and therefore needs opposite pass through Refrigeration and its ambient enviroment often are thoroughly cleaned, required high sanitary standard when to be maintained at operation or to handle food.
